Class notes
Scanned Notes
The main points of the lecture were
- Complex Boundary Layer Flows
Goals:
After this class you should be able to:
- Show how boundary layers grow in favorable or adverse pressure gradients.
Reading
- The class notes.
- BS&L, chapter 4
- Multi-Media Fluid Mechanics: Work through Boundary Layers: Laminar Boundary Layers.
Additional Readings:
For homework this week you are asked to solve for the velocity profile in
boundary layer flow along a flat plate with suction - one of the techniques used to
control boundary layer growth and separation. For a good short discussion of the
various approaches to boundary layer control, check out the link given
here. A really lovely picture of the
effect of suction on boundary layer separation over a wing may be found
here.
Another link at the same site (given
here)
has some interesting examples of experimental planes where the technique was used.
Demonstration:
Can Crushing and Bernoulli's Equation
